2. mL E L wn S S m., E D un un 2 To all whom it may concern: Be it knownthat I, RUDOLPH COOPER- sarrrri, a citizen of .the United States, and aresident of the city of St. Louis and State of Missouri, have invented anew and useful 'Improvement in Sofa-Bedsteads, of which "the followingis a specification.

Thisinventionorelates to sofa-bedsteads.

- Itfhas for its principal objects to produce.; a convertible sofa andbedstead of simple and compact-construction which is light and` formpart of this specificationan wherein..

*like* symbols refer' .to like parts Wherever `evoccur', Figure 1 is anendv elevation l1" "one of theend members ofthe sofa 25 f'main frameremoved; cFig. 2 is a similar "vietril showingv the device convertedinto a be'ds'tead; :F ig. 3 is a fra mentary view, lpartij/ 'in sectionand part y in elevation, vowin a pivot andbearing for thereversible-section .of the frame; Fig. 4 is a section on the line '4s-4of Fig. 3and Figs. 5 and G are fragmentary views, on an enlarged scale,v"showing" thev action of the supporting legs 'for the 'reversibleframe. Themain or body frame ofthe sofa com- Aprises; end members 1 anda stationary back to `which the endime'mb'ers are connected. Abase board3 connects the lower front portion of the'end members 1. As shown invthe 40 drawings, the end members 1 are inthe form ofV closed panels, butobviously the same may' be made as open frames; and, in so" far as thegeneral arrangement of the `main `frame of the sofa is concernechit may`be of an desirable construction.

I An u'' olstered cushion or seat Il is mounted on t e upper side of areversible pivotal frame 5. The front of the frame 5 is pref`erably.closed by a covering 6 which .isa con- .50"tinuati on-of thecovering material of the seat 4'. The'frame is -a box'frame, triangularin transverse sectmn. That 1s, 1t comprises vtriangularl end frames ormembers which are rigidly connected by suitable longitudinal members(not shown), and suit- 4i serramenti);

the frame laretp'rovi-ded' with outwardly extending trunnio's7 which arepivotally mounted in box'castings 8 secured to the inner sides of theend members 1 near the .front edges thereof. The end members arenormally supported at their inner corners on brackets 9 wliicharesecured to the inner faces of the end members 1 -Extensions 10" at I:thelower corners of the triangular end members ofthe frame 5 are pivotallyattached tothe corner extensions 11 of triangular end members of asecondary frame 12. A mattress 13, is mounted on the adjacent inclinedsides of the two coperati'ng frames 5, .12; ThisI mattress is preferablya continuous' 'flexible one vso that it will readily lfold at .thebreaking 'point between the two franies=5,"12. vThe second'ary frame Aissupported a't'its lowerinost corners by casterwheels 14' orrollei'sivhichrest 'upon the floor. The triangular-end members 'of the[secondary frame' `12 'are so proportioned with respect to those 'of thereversible frame 5, that when said-reversible frame is swung ablybraced. `The 4vertical end members ofl i over on its pivotsl 7 until its'normally 'inf' clined side onl .which the mattress' 13 is mountedassunfesla horizontal position,` shown in Fig.2', the=normally inclinedside of the secondary/frame on which themattress 13 is `-mounte'd alsoassumes hori! yzontal. position inthe same plane. ln this openedposition o'f'the two frames, the re"j -vers'ible frameis"supportednearits outeredge by legs or sumoorts 15v which are pivot? ally mounted'on'Athe opposite ,ends of the frame.4 ireferablvfsaid-legs each have alongitudinal slot lftherein which slidjlblfgT fits a headed studi 17projecting 'from fthe outer side ofthe frame member; Crlhe legs atingstuds are so arranged, that when the stud 17 is at the'bottor'n. of thesl0t,`1(, the stud 19 also restson the bottom of the notch 1,8. By this.anngeinent,` the legs 15` are held against accidental collapse, when theparts are 1n tlieposltion shown 1n Fig; 2.

15 also have notches-18 vinl their ends so as to i When the fran'les areopen as shown in Fig. 2, the pivotal connection between the parts 10 and1l o-i,E the respectivo tramos 5,

12 is nearly. in' Vertical alincmont with the axis of the pivot-stmlsoltl'u'nnions 7; and,

tionate leverage of the device is such that a great weight can besustained at or near the als said pivot points between the parts 10 and11A without tilting the reversible frame.

To open the device to make it into a bedstead and close the same backintoV .its normal condition as a sofa, the reversible frame can bereadily swun on its pivots and the secondary frame Wil accommodateitself to such movement owing to its pivotal connection with thereversible frame and its'arrangement of supporting rollers 14 which rollon the floor.

Obviously the device admits of c0nsiderable modification Withoutdeparting from my invention. Therefore, I do not Wish to be limited tothe specific construction and arrangement shown.

What I claim is:

1. A convertible sofa-bedstead comprising a main frame, areversibletriangular frame pivotally'mounted on said' main frame, and a secondarytriangular frame' -pivotally attached to said reversible frame,

said reversible frame being arranged and adapted to provide a supportfor the sofa seat in one of its positions and a supportA for the bedmattress in its other position.I and said secondary frame being arrangedand adapted to accommodate itself to; the movementof said reversibleframe and'form a. support'for the bed mattress in the same plane as thereversible frame.

2. A sofa-bedstead comprising a reversible frame which is triangular intransverse Section, said frame being pivoted at its opiposit'e ends, aseat mounted on one side of said reversible frame and a mattress mountedon the side of said frame opposite to that on which the seat ismounted-,and a secondary frame pivotally connected to said first.mentioned frame, said Secondary frame being also ltriangular intransverse section,

said secondary frame being so proportioned with iiespect to said first'mentioned frame,

that when said first mentioned frame is re.

versed and its side on which the mattress is mounted is brought into a.horizontal plane,

one side of the secondary frame also assumes a horizontal position inthe same plane, and when said first mentioned frame is in the positionwith the side on which the seatV is mounted in a horizontal plane, saidsecondary frame is folded under' said first. mentioned frame, and amattress on the side of said secondary frame which cooperates with themattress side of said first mentioned frame.
